I’ve been stuck on this week’s special for ages, don’t know how to proceed without seemingly guessing. Even if there is the odd square I’ve overlooked, I can’t imagine it’d set off a full on chain reaction.

Spoiler image of what I’ve got so far in the comments.
Assuming that you’re correct so far, in your first column, you can deduce that the 9 and the 5 are separated by the bottom-most X you have in place. With the 9(and maybe the 1) somewhere in the middle section and the 5 somewhere in the bottom section
Do you know what’s really stupid? I already saw that the 9 had to go there, I just forgot to do the overlap trick (I’ve only really discovered nonograms this week). Cheers!
